Acute Subdural Hematoma

The primary objective of this study is to establish a data repository permissive of quality improvement studies/observations specific to patients with Acute Subdural Hematoma and evaluate impact of surgical interventions like burr hole trephination, Craniotomy, Decompressive Craniectomy, and Middle Meningeal Arteryembolization embolization on survival outcomes.
